Creating and updating metadata schemas: about fairdatapoint HOT 3 OPEN

Hi @PderyckeSciensano, for SHACL the correct syntax would be sh:datatype xsd:float (which could be combined with sh:nodeKind sh:Literal, but that's probably not required). This would at least solve the validation part. For the form itself, I'm not sure if there's a widget for floating point input; @janslifka can you confirm or deny this?

Hi Kees, Thx for your answer. I tried the solution you suggested and have the following error: "Unable to update entity data.".


Just to better understand the scope of my question. If I run a SPARQL query with " FILTER (?lat >= 40.75 && ?lat <= 40.85 && ?long >= -73.98 && ?long <= -73.88)" how do I query against floats and not strings?

You can recast datatypes in SPARQL. For example: xsd:float(?variable))

You need to have xsd in your PREFIX

Also, be aware that the recasting is LOCAL! Unless you assign the recast value to a new variable, you will need to do the recasting in every clause of the query!

Hope that helps!
